This thread reminds me of something my mother used to say, "Marry in haste, repent at leisure."
She also used to tell me, "Choosing a mate is like choosing a pair of shoes. First you try them on, walk around the store. If at an point they bind, pinch, squeak, or rub -- Don't buy them. They will only cause you blisters, sore feet, and you will have to throw them away."
It is better to be alone than with the wrong person.
